I have a 250/100 with 5.36kWp of PV installed. The system can grid feed. The daytime loads are relatively low, but it looks like the charge controller is limiting to 2.5kW (50A). Charge current limit is disabled.
I have tried Keep Batteries Charged as well as optimized with batteries at 100%.
Charge controller float voltage 54.4V
Inverter charge setting 53.6V
Charge controller firmware version v1.39
Color Control firmware v2.23
Does the country standard affect the amount of power that can be grid fed? Country code: Other
